My boyfriend and I are currently a month into a 3-4 month trip in Europe and are finding it quite challenging to find suitable gas refills for our van. The gas runs both the cooktop and the fridge.
We have a Campingaz R907 cylinder and are out of gas in Poland, en route to Romania, Bulgaria and Montenegro where we plan to spend most of the next 2 months. We will pass through the eastern parts of Slovakia and Hungary today/tomorrow.

We were under the impression that Campingaz was easily available throughout Europe, but that doesn’t seem to be in case in any of the countries we plan to be in in the immediate future. We are wondering what our options are as
Is it possible to:

buy a different brand of gas cylinder that will fit the regulator we have (15mm screw in)?

change the regulator to one that is going to be more conducive to the gas cylinders that are available in the countries we are heading to? If this is possible, can we do this ourselves? Can anyone suggest names of stores from which we could buy the required equipment please?

Is the burner made by campingaz? if so, it might be calibrated to burn efficiently with a mix that should be 80% butane, 20% propane. If you can't refill with the same mix and only find 100% propane, there could be combustion issues where more harmful byproducts are released in your camper.
